Is your feature request related to a problem? Please describe

When searching for original soundtrack albums (films, series, video games, etc.), it may be difficult to find the soundtrack among the 25 results displayed during a search, it may even be impossible to find some original soundtrack in lidarr in this way!

Describe the solution you'd like

You should add a filter to display only the soundtracks when searching for an album. This way it will be easier to find the soundtracks and add them to the library.

By using the following query: releasegroup:(rambo) AND secondarytype:soundtrack (replacing "rambo" with the name of the soundtrack) in a search with the musicbrainz database, it is possible to isolate the soundtracks from other albums .

Describe alternatives you've considered

For now I'm searching directly on the site https://musicbrainz.org/search?query=releasegroup%3A%28rambo%29+AND+secondarytype%3Asoundtrack&type=release_group&limit=25&method=advanced

I add the albums in lidarr using their identifiers like this: lidarr:83c566c2-f410-4159-97f0-3e255b840e79

This is a tedious method, but can be made easier in a lidarr update

Anything else?

Are there currently any existing filters that you use on Lidarr sarch, or would this be a new syntax for filtering searches?
